Southern Sydney Freight Line

Sydney, Australia

Controlling noise and vibration on a suburban freight route

A major freight rail company in Australia proposed a 28-kilometre long dedicated freight line through the southern suburbs of Sydney, primarily to carry freight to and from the Port Botany container terminal. The project involved the prediction, assessment and control of noise and vibration associated with the route, which passed primarily along an existing rail corridor.

We developed a major rail noise prediction model and predicted noise levels at all noise-sensitive locations adjacent. Since the proposed line passes over a number of bridges, our work also involved the analysis of bridge vibration and radiated structural noise so as to be able to predict noise levels in the area with a high degree of accuracy.

At many locations along the route, we proposed the installation of rail side noise barriers. We continue to conduct assessment and monitoring work associated with the construction phase of the project.
